Create charts from CSV or manual data

iuerp helps you turn structured data into readable charts without installing spreadsheet software or uploading files. Paste CSV with a header row, or enter values directly in the manual table editor.

The chart maker detects your column names, identifies likely numeric and category fields, and gives you simple mapping controls for chart axes.

Why use a browser-based chart maker?

A browser-based chart maker is fast, accessible, and convenient. It works well for quick reports, educational charts, blog visuals, marketing summaries, and internal analysis.

Because the tool is privacy-first, your chart data is processed in browser memory rather than being sent to a remote server.

Supported chart types

The first version supports bar charts, line charts, pie charts, and scatter plots. Bar charts are useful for comparing categories, line charts show trends, pie charts show parts of a whole, and scatter plots help compare numeric relationships.

Future versions can extend the same architecture to support doughnut charts, radar charts, stacked bars, histograms, area charts, and bubble charts.

How to create a chart

  1. Paste CSV or enter table data.
  2. Choose a chart type.
  3. Map your category and value columns.
  4. Customize the title, subtitle, color, legend, and line smoothing.
  5. Export the finished chart as PDF or PNG.

Privacy-first chart generation

Your CSV text, manual table data, chart labels, and chart values are not uploaded to our servers. The chart is generated locally in your browser.

No account is required, and the application does not need a backend database to store your charts.

Export charts as PDF or PNG

Use Export PDF to open your browser print dialog and save a clean chart report. Use Export PNG to download the chart canvas as an image file.

Both export options happen locally from your browser, keeping the workflow simple and private.
